For example, the average human gestation period is 38 weeks. Gestation may normally last anywhere from 37 to 42 weeks, however, and be considered well within the healthy range. Any child born before 37 weeks is considered preterm, and this can be accompanied by any number of health risks.
Gestation is the period of time when something is conceived and developed. The gestation period for human babies lasts nine months. Gestation comes from the Latin gestare, which means to bear, or give birth to. We can talk about the gestation of fetus before it's born, but we also use gestation to talk about ideas.
